Matthew Poole and continuators on Ephesians 2:6

6 And hath raised us up together , and made us sit together in heavenly places in Christ Jesus .

Either this may be understood of a farther degree of Spiritual Life in the progress of Sanctification vouchsafed to Believers in this World, or rather of the Resurrection of the Body which is said to be raised together with Christ, because it is to be raised by the same Power that raised him up, and by virtue of his Resurrection, in which we have Fellowship with him as being united to him.

As our Head, and Representative. Our Spiritual enlivening, v. 5. we have not onely fundamentally in Christ when restored to life, but actually begun in our selves in our effectual calling, but the Resurrection of our Bodies, and our sitting in Heaven we have not as yet actually fulfilled in our selves, yet have it in Christ our Head, who rose for us and we in him, and sits in Heaven for us, and we in him may be said to sit there too by reason of our Union with him, and being members of him.
